Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). NDVI is a ratio of different light wavelength reflectance which can be used to map the density of green vegetation.
Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations.
This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice.
Students analyze a graph that illustrates the change in global surface temperature relative to 1951-1980 average temperatures.
Students connect day/night and seasonal cycles with albedo in the Arctic region.
Students review a video showing a global view of the top-of-atmosphere shortwave radiation from January 26 and 27, 2012 and answer the questions that follow.
Students will analyze a graph showing the variation of energy imbalance on Earth over the year along different latitudinal zones and answer the questions that follow.
Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.
By investigating the data presented in a model that displays extreme summer air temperatures, students explain energy transfer in the Earth system and consider the impact of excessive heat on local communities.
